TMS320F28379D: GETTING TROUBLE WHILE SWEEPING THE SINE WAVE FREQUENCY

Niraj,

It depends on what inputs provided for SFRA_F32_config function such as injection amplitude, ISR frequency, number of frequency points, frequency sweep start? May I know the configurations?

This function is used to set the frequency range- "SFRA_F32_initFreqArrayWithLogSteps"

We can manually edit the frequency points as follows too:

SFRA_F32.freqVect[0], SFRA_F32.freqVect[1], .................................., SFRA_F32.freqVect[n-1] where n is number of frequency points.

Thanks & Regards,

I did referred to this thread to generate Sine wave using SGEN library.

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/879207/ccs-launchxl-f28379d-ccs-launchxl-f28379d-generating-100khz-sine-wave-using-sgen-library

void sweep(void){
f=f+10;
sgen.freq = ((long long )f * (long long )2 * 2147483648LL)/((long long)fmax);}

and this is the function which I'm using to sweep the frequency by 10Hz

Niraj,

This is regarding SGEN Library and related to SFRA library. I will let SGEN library owner to reply regarding this.

Thanks,

Shashank

Hello,

Unfortunately there is no expert currently able to support the SGEN library, please try to use the reference generator in the Digital Control Library.
